1,209,852. Patented Dec. 26, 1916.

rotatable post 7 is preferably hollow and of angular or elbow formation,therebyproviding a vertical shank portion 8"and"a*hori-' zontal arm portion 9. This shank portion 8 of the post maybe formed, as" shown',with an annular rib or shoulder 10 for. abutting against the upper edge of the sleeve 6 carried by the cap, while the end'portion there of extends down through the sleeve and terminates at the inner'side of the cap 5. This lower extremity of the shank 8 preferably carries a fiber switch arm 11 which is substantially attached to the internal end of the post preferably by clenching the attaching projections P of the latter'into the end ofthe fiber switch arm. That is to say, the lower end of the shank 8, which forms the internal end of the rotatable "post, may be provided with the fastening extensions P, as shown in Fig. 4, whereby the latter may be inserted in suitable openings formed in the fiber piece and then bent over or clenched to rigidly attach the fiber switch piece to the post.

: For the purpose of providing the desired freedom of movement between the rotatable post on the relatively fixed cap 5 whereby the former may be swung through .an are of approximately 180, thereis' provided a coiled friction spring 12 or'equivalent means surrounding the lower end of the shank 8, and confined betweenlthefnpper side ofthe switch arm 11 anclgthe interior face of the cap 5, as clearly shown in Fi'gia 'With this arrangement, it will be apparent that the post 7 may be rotatedjthrough the required are with enouglnfreeddm to preventunlimited swinging of thes'witch arm, which,

of course, is not desirable. 4O

The substantially horizontal ,ar-m portion 9 of the post is providedatits extremity with the suitable reflector shade 13,:ind is also formedwith aflthreaded lamp socket portion 14; for receiving the plug 15 of an electric lamp L. In connectionwith this portion of the apparatus, it willbe'pbserved that the center contact of the lamp socket may be a coil springlfi or the likewhich is secured to aninsulatedbase member 17 by a metallic fastening 18,,or other convenient means. The provision, of the spring. 15 as the centercontact forthe socket makes ample provision forthe'slightyariation in the length ofthe screw plug portion of the lamp L, and tends to maintain an efiicieIItQ Iitact betweenf the battery, and the lampi ;.Ac-

cording y, it will be'apparent that the novel and distinctive feature of the presentfinvention isthe provision of a container having a detachable cap carrying a rotatable switchingpost'having at one end. an, electric lamp L and at itsother enda switching arm 11,

.which may be limited in its movement by means of the stoplug 19 carried by theinner side of the cap 5. It may also'be'noted arm 9'and reflector shade 13 to move clear of the. record .table T when the device is in position" on the top of the cabinet to permit of the placing of the record on the table, and

also removing the same therefrom, and when in'position over the table, closes the circuit. The light from the lamp is suflicient to enable the operator to see to'place the needle in the stylus holder if the machine is being played in the dark.

The container body 1 is adapted'to receive a suitable electric battery B of any well known dry cell type 1 having one pole 20 thereof in contact with 'the'cylindrical side at 24 with the screw l'8 which forms apart of the center contact '{of the lamp socket.

Thus, it will be apparent that since the plug le' of the lampll is in metallic contachwith the shell I4, and the center contact" of the is connected with the spring 16, the circuit is closed fromthebattery B'through the c onta'ct ofthe portion 22 of the wire 23 with the contact member 21'L'of the battery. v

This is showndiagrannnatically' in Fig. 5. That'is'to say, the battery B is earthed as at 20 by'touchi ng the casing, and the plug 15' of 'tlte' lanip L is also earthed byv connection w th the metallic shell 14; of the lamp socket,

while the centerv plug contact. is insulated .fro njithe' arm'and is connected with the batterycontact 21 by means of the insulated wire 23 whose lower end is held, in the insulated switch arm-11, but exposed for contact, for a portion'of its length, with the arm .1; o t e ba ery- 'When'" the s itching post 7 is a the position'shown inffull lines in Fig. 2; the circuit t'o-the lamp is 'closed,,since the portion 22 of the 'wire 23 is in contact with the contact .member 21 of the battery. However, when the switching post is shifted to'the dotted line positi0n, the circuit is broken, since the switch arm 22 has been swung through an arc of sufficient magnitude to remove it from the-contact 21. The battery B may be held in a fixed position in the container'2 by any suitablemeans, preferably by means of the angle brackets 25, shown in Fig. 3, which.

will prevent the metallic portion of'the battery coming in contact with the side wall 2 ble. However, it will be understood that of the container and thus forming a short circuit. I

From the foregoing, itwill be apparent that the present device may be placed adjacent the record table T of a phonograph, so that the attaching extension 3 may extend beneath the record table. In this connection, it may be noted that when theear 3 is employed, in order to attach the device to the cabinet, the record table may be removed and the attaching plate secured to the top of the cabinet by any suitable'fastening, so that when the table is replaced on the center spindle, the attaching means will not be seen. Also in case it is desired to later remove the device, the screw holes will not be noticed, as they will always be under the record taother means may be employed to this end. It will also be clear that when the switching post is rotated toward the initial point of application of the reproducer of the record, the lamp L becomes lighted, but when turning the arm away from the table to permit of the removal of the record, the light is extinguished.

Without furtherdescription, it is thought that the many features and advantages of the present invention will be readily apparent, and it will, of course, be understood that various changes in the form, proportion and minor details of construction may be resorted to without departing from'the spirit of the invention or scope of the appended claims. g I
